This was my first smartphone and I loved it. It had its problems but all phones do. Performance This phone worked great for the first year and a half. I loved the thing. It worked very well and I was able to do a lot on it. Voice Quality Great voice quality. I never had any problems making phones calls on it. Better than a lot of phones I've had. Battery Life This phone didn't have a great battery life, especially after a couple months it seemed to die even faster. Even my extended battery that I bought only last 24 hours when it was advertised for 72 hours. Durability This phone was pretty durable. I was pretty rough on it and it never cracked or broke in any way except the battery door is a little loose. It still works to this day. Ease of Use Very easy to use. The little green android guy is even there with directions when you first get the phone. Design Very cool design and look to it. That was one thing that drew me to purchase it. Even the design of the software on the phone was very cool.
